An induction furnace is a type of electric furnace that uses electromagnetic induction to heat and melt metals. It consists of a coil of copper wire through which an alternating current passes, creating a magnetic field. This magnetic field induces electrical currents in the metal placed inside the furnace, generating heat due to resistance. Induction furnaces are commonly used in foundries and metalworking industries for their efficiency and ability to melt various metals, including steel, aluminum, and copper. They offer precise temperature control and reduce energy consumption compared to traditional furnaces, making them a popular choice for modern metal production.
